CHARLES H. PHILLIPS AND EDWARD G. GREENE, OF EAST NEW YORK, N. Y.

BLIND-SLAT ADJUSTER.

SPECIFICATION forming part of Letters Patent No. 254,235, dated February 28, 1882. Application filed November 21,1881. (No model.) I

To all whom it may concern:

Be it known that we, CHARLES H. PHIL- LIPS and EDWARD O. GREENE, both of the town .of East New York, county of Kings, and State of New York, have invented a new and useful Improvement in Adjusters for Blind- Slats; and we do hereby declare that the following specification, taken in connection with the drawings annexed to and forming part of the same, furnishes a full and clear description thereof, sufficient to enable'those skilled in the art to which it pertains to make and I operate the same.

Our invention consists of an adjustment for turning the movable slats of window-blinds.

In the drawings, Figure l is avertical crosssection through the lower portion of a window: frame and blind, showing our said invention. Fig. 2 is a vertical cross-section through the same, showing a single blind-slat with our invention attached thereto.

Most window-blinds now in use in our cities have the slats thereof movable by being pivoted at each end, so as to increase or diminish the amount of light or air suffered to pass through the same while the blind is closed in front of the window.

The usual method of changing the adjustment of the slats is by having a narrow strip of wood fastened to the middle of the edges of said slats, so that by opening the window and placing the hand upon the perpendicular strip all the slats connected thereto can be moved equally and simultaneously.

Our invention has for its object the adjustment of said blind-slats from the inside of the window without raising the sashes thereof.

In Figs. 1 and 2, (t represents one of the movable slats. The window-sillis shown at 0, the lower rail of the blind at p. The side rail of blind, to which the hinges k are attached, is shown at m.

b is a thin strip of metal, which we attach to the edges of the slats a by a small pin or wire at the ends of the slats adjacent to the window-frame it, this strip serving the same purpose as the wooden strip ordinarily placed at the middle of the slats. Upon this strip b, and projecting therefrom horizontally at right angles thereto, is affixed a stirrup, c, of sub- This stirrup is furnished with a slot to receive the end or finger d of the lever c, with room for lateral play therein.

At 6 is a lever or rod running through the window-frame h, with a handle, g, at one end upon the inside of the window-frame, for turning the lever, and provided at the other end with the finger d, for operating upon the stirrup 0 outside the window-frame.

Upon the inside of the window-frame h is a catch, t, with a beveled. edge, against which the handle '9 bears. This beveled surface of the catch terminates in a flat top, by which the handle 9 is held in position.

The spring 8, encircling the rod 6 within the window-frame It, serves to press the rod 8 and its finger d forward to engage with the stirrup 0 when the handle 9 is not held by the stop it, the rod 6 being free to play longitudinally within certain limits.

It is obvious from the foregoing description that when the blind is closed the turning of the handle 9 will cause a corresponding movement of the finger d, which will move the slats a as desired. The finger d, not being fastened within the slot of the stirrup c, is withdrawn from the slot on the opening of the blind on its hingelc. The blinds may be closed irrespective ot' the positionof the finger d, and the latter then inserted in the stirrup c by drawing back thehandleg, turningthehandle until the finger d is opposite the slot in the stirrup 0, and then allowingthe finger d to be inserted in the slot by the forward action of the spring 8, and the apparatus is in position again for adjusting the slats.

As the sides of the slats a are turned from a is obvious that they will be thrown toward the rod 0, and the stirrup 0 will travel up the finger d and press against the fiat base of the finger, which connects it with the main rod 6. The spring 8, operating to press the rod in a contrary direction, keeps the handle g frictiontight against the bevel of 15, holding the slats firmly at any angle at which they are turned, while they can be firmly locked by turning the handle 9 to bear on the flat part of it.

Having thus described our invention, we do not claim broadly all apparatus for adjusting said slats from the inside of the window, but

What we claim as our invention, and desire attached, substantially as and for thepurposes to secure by Letters Patent, isdescribed.
